Straight type fluorescent lamp device with light reflecting plates

Abstract

The fluorescent lamp device has reflecting plates, its body is made by direct extrusion, and it can be cut into any desired length to match with straight-type fluorescent tubes of any length specification, and tube holders, one each at each end of the body of the device; by means of the attachment of light reflecting plates and glare-proof plates one can increase the intensity of downward straight light by 1.7 times and substantially preclude damage caused by glare of light.

What is claimed is: 
     
       1. A substantially linear fluorescent lamp device comprising: a lamp body, said body defining, when considered in cross section, a channel of semi-circular configuration, with the interior concave wall thereof including a glossy surface to enhance the reflective properties of said lamp device;   said body also having an upper exterior groove formation defined by hook-shaped flanges to reinforce said lamp body and for the concealment of respective electrical wires, a central aperture in said upper groove formation for passing therethrough respective electric wires;   said body including exteriorly at each channel wall terminus a round formation for a respective light reflecting plate; and   said lamp body further including exteriorly at each channel terminus a retaining groove formation for a respective glare-proof plate;   said round formation and said retaining groove formation extending substantially along the full length of said lamp body;   for each end of said lamp body, a tube holder for a respective tube socket end-formation of a respective fluorescent tube, wherein at least one of said tube holders defines a holder for a respective starter;   for each round formation at least one light reflecting plate, each light reflecting plate having a longitudinal hollow cylindrical flange formation adapted to be compressibly inserted in the round formation of said lamp body; each flange formation extending substantially along the full length of a reflecting plate;   a plurality of glare-proof plates strung together along a respective soft wire, each one of said glare-proof plates having a rectangular configuration but including an upper semi-circular recess formation, and upper retaining formations adapted to interlock with the retaining groove formations of said lamp body, and a line gap for a respective soft wire, said line gap being of sufficient size for receiving exclusively said soft wire; and   a soft wire secured at respectively end-wise located glare-proof plates;   wherein the lamp body and the light reflecting plates are formed by direct extrusion and which can be cut into desired lengths to match the length of the respective preselected fluorescent tube.   
     
     
       2. The tube holder according to claim 1, comprising a cylindrical outer sleeve, said sleeve having a slot for electric wires to extend therein, two bolt holes for respective bolts, for securement of said outer sleeve at said lamp body, and also having interiorly three peripherally distributed pin holes;   a lamp socket freely moveable disposed in said outer sleeve, said lamp socket having at least three exterior recess formations respectively matching with said three pin holes of said outer sleeve, said lamp socket on the back side having threaded holes for respective bolts for the securement of electric wires, and said lamp socket also on the back side having a depression formation for the location of a respective spring, and said lamp socket having on the front side holes for respective connection legs of a respective fluorescent tube, wherein when the connection legs of a fluorescent tube are inserted into the front holes of said lamp socket, the connection legs will contact the bolts on the back side of the lamp socket to close an electric circuit to turn on a respective fluorescent tube; and   said lamp socket comprising one bolt hole each on both sides of the depression formation, and each bolt hole comprising at its outer side a retaining cutting for bare electric wire to be placed therein and being retained in place by a respective bolt;   a spring positioned within said outer sleeve to extend between said outer sleeve and said lamp socket and adapted to bias said lamp socket outwardly and into contact with the respective fluorescent tube as aforesaid; and   a ring-shaped stop plate, said stop plate having three pins on its back side for matchingly insertion respectively into the three pin holes of said outer sleeve, but so as to keep the lamp socket moveable within said outer sleeve and to preclude inadvertent removal of said lamp socket.   
     
     
       3. The tube holder according to claim 1, wherein the other end of a preselected fluorescent tube is adapted to be attached at a starter holder fixed with two pieces of spring leaves by two pieces of bolts and then covered with a cover plate, said spring leaves being of the flat type with each end facing upward and being used as contact points to connect a respective starter. 
     
     
       4. The lamp device according to claim 1, wherein said glare-proof plates are strung equidistantly at respective soft wires and are hung at said retaining groove formations of said body but with substantially free movement. 
     
     
       5. The lamp according to claim 1, and further including holding clamps, each of said clamps having an inverted "U" shape with respective lateral hook flanges, and being made of elastic steel, comprising interiorly a respective hook-shaped plate on each end and exteriorly a longitudinal bolt hole, wherein at least one clamp can be fixed to a respective ceiling with a screw through the bolt hole, but allowing the lamp body to be attached to the clamp by means of its hook flange. 
     
     
       6. The lamp according to claim 5, wherein said clamp is a cross clamp adapted to extend over two adjacent located lamps, and comprising exteriorly a longitudinal bolt hole and interiorly two pairs of hook plates. 
     
     
       7. The lamp device according to claim 1, and further including a clamping device which includes a steel plate welded centrally at a respective depressed part to form a slide way which can be sufficiently placed inside said groove formation of the lamp body and the respective ends of said clamping device can be sufficiently deep inserted into the respective round holes of said lamp body.
